我在使用SXSSF poi api生成有效的xlsx文件时遇到问题。 如果我使用以下代码生成正确的excel文件: 工作簿wb = new XSSFWorkbook(); 但如果我使用,则失败: SXSSFWorkbook wb = new SXSSFWorkbook(100);
错误:删除记录:来自/xl/comments1.xml部分的评论(评论)
请帮我理解代码有什么问题。我希望使用SXSSF api生成带有单元格注释的excel文件。
实际代码:
public static void main(String[] args) throws Exception {
// Workbook wb = new XSSFWorkbook();
SXSSFWorkbook wb = new SXSSFWorkbook(100);
Sheet sh = wb.createSheet();
for(int rownum = 0; rownum < 1000; rownum++){
Row row = sh.createRow(rownum);
for(int cellnum = 0; cellnum < 10; cellnum++){
Cell cell = row.createCell(cellnum);
String address = new CellReference(cell).formatAsString();
cell.setCellValue(address);
setCellComment(cell,address);
}
}
FileOutputStream out = new FileOutputStream("comments.xlsx");
wb.write(out);
out.close();
}
protected static void setCellComment(Cell cell, String message) {
Drawing drawing = cell.getSheet().createDrawingPatriarch();
CreationHelper factory = cell.getSheet().getWorkbook()
.getCreationHelper();
// When the comment box is visible, have it show in a 1x3 space
ClientAnchor anchor = factory.createClientAnchor();
anchor.setCol1(cell.getColumnIndex());
anchor.setCol2(cell.getColumnIndex() + 1);
anchor.setRow1(cell.getRowIndex());
anchor.setRow2(cell.getRowIndex() + 1);
anchor.setDx1(100);
anchor.setDx2(100);
anchor.setDy1(100);
anchor.setDy2(100);
// Create the comment and set the text+author
Comment comment = drawing.createCellComment(anchor);
RichTextString str = factory.createRichTextString(message);
comment.setString(str);
comment.setAuthor("Apache POI");
// Assign the comment to the cell
cell.setCellComment(comment);
}
答案 0 :(得分:6)
我遇到了同样的问题,并通过在Comment
上设置行和列属性来解决它。
如下修改示例中的setCellComment()
方法可以解决问题。
protected static void setCellComment(Cell cell, String message) {
...
// Create the comment and set the text+author
Comment comment = drawing.createCellComment(anchor);
RichTextString str = factory.createRichTextString(message);
comment.setString(str);
comment.setAuthor("Apache POI");
// Set the row and column here
comment.setRow(cell.getRowIndex());
comment.setColumn(cell.getColumnIndex());
// Assign the comment to the cell
cell.setCellComment(comment);
}
我通过查看XSSFCell
类中setCellComment()
方法的来源发现了这个解决方案。 SXSSFCell
中的相应方法未设置行或列。
